Labels

Labels provide an easy way to categorize the issues or merge requests based on
descriptive titles like bug, documentation or any other text you feel like.
They can have different colors, a description, and are visible throughout
the issue tracker or inside each issue individually.

With labels, you can navigate the issue tracker and filter any bloated
information to visualize only the issues you are interested in. Let's see how
that works.

Create new labels

Note:
A permission level of Developer or higher is required in order to manage
labels.

Head over a single project and navigate to Issues > Labels.

The first time you visit this page, you'll notice that there are no labels
created yet.

Creating a new label from scratch is as easy as pressing the New label
button. From there on you can choose the name, give it an optional description,
a color and you are set.

When you are ready press the Create label button to create the new label.

Default labels

The very first time you visit the labels area, it's gonna be empty. In that
case, it's possible to populate the labels for your project from a set of
predefined labels.

Click the link to 'Generate a default set of labels' and GitLab will
generate them for you. There are 8 default generated labels in total:

bug

confirmed

critical

discussion

documentation

enhancement

suggestion

support

Labels Overview

You can see that from the labels page you can have an overview of the number of
issues and merge requests assigned to each label.

Prioritized labels are like any other label, but sorted by priority. This allows
you to sort issues and merge requests by label priority.

To prioritize labels, navigate to your project's Issues > Labels and click
on the star icon next to them to put them in the priority list. Click on the
star icon again to remove them from the list.

From there, you can drag them around to set the desired priority. Priority is
set from high to low with an ascending order. Labels with no priority, count as
having their priority set to null.

Now that you have labels prioritized, you can use the 'Label priority' and 'Priority'
sort orders in the issues or merge requests tracker.

In the following, everything applies to both issues and merge requests, but we'll
refer to just issues for brevity.

The 'Label priority' sort order positions issues with higher priority labels
toward the top, and issues with lower priority labels toward the bottom. A non-prioritized
label is considered to have the lowest priority. For a given issue, we only consider the
highest priority label assigned to it in the comparison. (We are discussing
including all the labels in a given issue for this comparison.) Given two issues
are equal according to this sort comparison, their relative order is equal, and
therefore it's not guaranteed that one will be always above the other.

The 'Priority' sort order comparison first considers an issue's milestone's due date,
(if the issue is assigned a milestone and the milestone's due date exists), and then
secondarily considers the label priority comparison above. Sooner due dates results
a higher sort order. If an issue doesn't have a milestone due date, it is equivalent to
being assigned to a milestone that has a due date in the infinite future. Given two issues
are equal according to this two-stage sort comparison, their relative order is equal, and
therefore it's not guaranteed that one will be always above the other.

Subscribe to labels

If you don’t want to miss issues or merge requests that are important to you,
simply subscribe to a label. You’ll get notified whenever the label gets added
to an issue or merge request, making sure you don’t miss a thing.

Go to your project's Issues > Labels area, find the label(s) you want to
subscribe to and click on the eye icon. Click again to unsubscribe.

If you work on a large or popular project, try subscribing only to the labels
that are relevant to you. You’ll notice it’ll be much easier to focus on what’s
important.

Create a new label when inside an issue

There are times when you are already inside an issue searching to assign a
label, only to realize it doesn't exist. Instead of going to the Labels
page and being distracted from your original purpose, you can create new
labels on the fly.

Expand the issue sidebar and select Create new label from the labels dropdown
list. Provide a name, pick a color and hit Create. The new label will be
ready to used right away!

Assigning labels to issues and merge requests

There are generally two ways to assign a label to an issue or merge request.

The first one is to assign a label when you first create or edit an issue or
merge request.

The second way is by using the right sidebar when inside an issue or merge
request. Expand it and hit Edit in the labels area. Start typing the name
of the label you are looking for to narrow down the list, and select it. You
can add more than one labels at once. When done, click outside the sidebar area
for the changes to take effect.

To remove labels, expand the left sidebar and unmark them from the labels list.
Simple as that.

Use labels to filter issues

Once you start adding labels to your issues, you'll see the benefit of it.
Labels can have several uses, one of them being the quick filtering of issues
or merge requests.

Pick an existing label from the dropdown Label menu or click on an existing
label from the issue tracker. In the latter case, you also get to see the
label description like shown below.

And if you added a description to your label, you can see it by hovering your
mouse over the label in the issue tracker or wherever else the label is
rendered.
